To all whom it may concern:

Be it known that LJAMns E. RALSTON, a citizcn of the United States, residing at New York city, lllanhattan borough, county and State oi NewYork, have in vented certain new and useful Improvements inDoodorizing Apparatus, of which the following is a clear,

full, and exact description.

This invention relates ton deodorizing apparatus, the

object being to provide a simple and effective apparatus for installation in factories, abattoirs or in any place containing foul or objectionable odors or contaminated air. I l W i To these and other ends which will hereinafter appeer, my invention comprises the novel features-oi improvement, and combination and arrangement oiparts which I will now proceed to describe and finally claim,

reference helm" had to the accom an in drawiiws D Y b b l forming part hereof, wherein Figure 1 is a longitudinslcentrsl section of a deodor izingnpparatus embodying myv improvements, the

piping and accessories being partly in section and the blower and connecting pipe being in elevation; Fig. 2 illustrates, in side elevation, 23. modiiied arrangoment of the tanks with r spect to the bloWeq Fig. 3 is an enlarged sectional plan view, the section being taken .on a line a-a in Fig. 1; Fig. 4 is an enla rgodlsectionnlplan view, the section being taken on a line Z2-b in Fig.1, and shows the perforated plate in the bottoni oi the distributing iunnel; Fig. 5 is an enlarged fragmentary view otthe bottom edge of the funnels; Fig. (l is an onla-rgcd sectional plan view, the section being taken on a line cc in Fig. l, andshows the autoinaticaliy controlled inlet-pipe; and Fig. 7 is an enlarged iraginentary vertical sectional view, the section being taken on a line lld in Fig. 6.

Like nurncrals of reference are intended to indicate corresponding parts in the several views.

.Relorring to thedrawings, the numeral 1 indicates a blower, which is driven by any suitable source of power (not shown) by'the bolt 2} The blower is of the usual order, the intake being at 3. A The air or gases which ai'e drawn in through the opening 3 are forced by the fan 4 of the blower through the pipe 5 and into a saturator (S. Withinthe saturator 6 I place :i'sprayiug [device 7, which cornprises a plurality of spiders 8, 9

' and it), the some heingconnected hy nipples 11 and 12 and fed by a watorpipe 13, a controlling valve being placed in the pipe 13, As many spiders rnay be used as desirable. Each of said spiders comprises arms 15 perforated as at 16 with any desirednunuher of holes, the arms lwing perforated on each side, and said arms are connected to fittings l7, which in turn receive water from the connected pipes, the lowest fitting being plugged at the bottom thereoi. By referring to Fig.

3 it will be seen that the spiders 8, 9 and 10 are out of ztlin'emcnt to an extent sufficient to cover orcontrol the area of the sa'tnratortankfi. Between the spraying device 7 and the eXhaust-pipe o oi bldwer l;I place a plurality of obstructing screens 'l8,which tend to cause the water from the spraying device 7 to' form a.

' l ilm through which the air orgtises fiOl'llIthP pipe 5 must pass. v The water will finally drip or iall into the trap 19, and as the tmp 'is of the' ordinary type-the water will form a seal, asat 20, but as the flowof water will be constant there will always be a flow through the 'ove 'flotwpipc 21, which may he carried away in any suitable manner; The seal, however, "will always remain. v

When the air or gases from the blower have passed through the screens 18 they will flow upwardly-through the pipe 22 into the spreading funnel 23which is'situated adjacent to the bottom of u ujwdsrnin tank 24. The bottom of the funnel 223 provided with it perforated plate 25 (see Figs. ,4 and 5), the perlrnutions hnying fitted therein short nipplc s 26. When onair iii-gases enter and till the said funnel 23, they ill flow out through said nipples, whereby the flownfthdtfir or gases will be divided into numorous small jets. Within the tank 24, and to a heightsui'licient to immerse the plate 25, 1 place a dcodon'zing element??? Said element willho automatically supplied, as 'will herein When tho dw'rdorixing solution has become usefvss through continued use, it nuivlw dmwnoff through the pipe 2.) irnd a fresh supply put in q lt'henthe air or gases luivc'passcd throughlhudvodorizing' solution and up inlu llubody oi the tank .Z-l'th'oy will he curried off llrrough the pipe Ill) and exhausted into the funnel 31 located in a washing tank 32. 'lhv'l'unncl3lisa'dripiirain of the funnel 223 in tank ZZ-l. and \i'ilhtllvi'vloivnot he described in dot-.iil. Within the lunk 32 water is cont-allied, us al 33, the water prvl'vi'ahly entering through a pipo'ii l and flowing out through nn'ohtiot 35.

'lhc onl'lct 35 is of sullicic'nt length to hoop-tho water at n predetermined height sullicicnt'to kvdp'lholmttoru oi the funnel 3] immersed. When the air or gases puss through the watcr. any'rvsiduul odorswill 'lw-nushcd thcreizormzurd lln-purilicd niror gnsoswill issuc'through the exhaust passage Ill; and run he conveyed 'uwu'y in suitable manner. I

Fig. l illustrates tho device an installed in a room and operates as ioll ows: 'lho ioulair will be sucked into the I blower 1 through the opening 3, and then into the Baturatingtank 6, where it will come in contact with water,-

' as hasben stated. The air will absorb much of the 5 water as itcan and will then pass to.thc deodorizer,

where the impure elements will be destroyed. The

object of saturating the air with water is to prevent the air irompassing toithe deodorizer in too dry a state, in

which case the air would absorb the dcodoriaer and carry some of'it with it, but by saturating the air first,

it cannot absorb any of the deodorizer, and consequently the deodorizer acts upon the impurities only.

After having passed through the deodorizor the air is thenipassed through the water in tank 32, and any of .16 th'ideodorizer gases that may be carried along with it will be absorbed by the water.

In the modified arrangement shown in Fig. 2, the blower 11's placed between the'saturator 6 and diode 'odorizer 24 and connected by the pipe 54 In this arrangom nt'thegases are drawn through the saturator 6 into the blower 1 and then forced through the tanks 24 ;and 32. If it is desired to connect the apparatus, for instance, to a kilnoi a Crematory (represented by A in 2), in which hot gases are created, the blower will 25 draw the hot gases throughthe water in tank 6 and cool as well as saturate same, thus preventing the destruction of the blower as well asrendering the gases more susceptibleto the deodorizing element.

In order to automatically control the supply of deodori zing-liquid, i provide a valve-controlled inlet'pipe 37 provided with a valve 38, a ball 39 actuating the valve through the agency of lever 40 (Figs. 6 and 7). When tho doodorizing liquid is at the required height, as at 41 Fig. 7), the valve 38 will be closed, thereby preventing the further flow of the said liquid, and when the liquid lowers, through use, the ball will fall, thus opening the' valve again, as shown by dotted and (lash lines 42 in Fig. 7. Liquid is supplied from any suitable source through a pipe 43.

Although the air or gases from the blower 1 will be under pressure, such pressure will not be sulliciont to force the water-seal 20 from the trap 19, as the air will be carried away as rapidly as it is forced into the tank 6. l

Having now described my invention, what I claim' and desire to secure by Letters Patent is: v

A deodorizlng apparatus comprising a saturating tank. a deodorizing tank. and a washing tank, an air spread ins tunnel in said deodorizing tank provided with a per-' i'orated bottom, the perforations in said bottom being fitted with nipples. said deodorizing tank being provided with an inletduct for the passage of a deodorlzing liquid. :1 rotain; the water at a predetermined height above (be portorated bottom of said funnel, an air inlet for said saturating tank, an outlet therefrom communicating with the funnel in the dcodorizing tank, an outlet from said doodorizing tank communicating with the funnel in said washing tank, and an outlet from said washing tank.
